Ratings and Reviews
Good
Good app.. The only complain ill make is after opening the OKN strips if i need to go back to the menu containing amsler grid , i can only do so after i quit and close the application and open it again.. But its a minor complaint and i like the app.
Good, but needs some improvement
My vision therapist recommended this app to help with eye stretches. It’s good, but I wish I could change the direction the bars move. I have to do this exercise with a patch on because my eyes don’t track together. So I’d like it if the bars could travel left or right and up or down.
Developer Response ,
Hi JobbbieBo,
You can change the direction of the bars by swiping on the screen in the opposite direction against how they're moving.
Also if you lock screen rotation on your device, you can physically rotate your device to control how the bars are moving.
OKN strips
This works quite well. Tap the screen to make the strips go faster. Level 1 through 5. I’m using this app to treat my nerve/ muscle paralysis in my left eye. It was recommended by my therapist. This exercise and time and hope.
Developer Response ,
The strips should cycle through speeds by tapping on the screen. If you're having problems with that, please contact oknstrips@thomasalvarez.com so we can work with you to try and solve the problem. Thanks.
